Let r and s be the roots of y^2 - 19y + 7. Find (r-2)(s-2).
Use the following to find the two roots:
\(y_{\pm}=\frac{19\pm \sqrt{19^2-4\times1\times7}}{2\times1}\)
Let r = y+, say, and s = y-
Can you take it from here?
i still dont know
Well I not surprised you not know because everyone here except you have done your homework. Your brain muscle is about the size of a peanut because you never use it.
There is no use overloading your brain now.
